Having thus declared how much the length of mens lives conduced unto the populosity of their kind, our second foundation must be the large extent of time, from the Creation unto the Deluge, that is (according unto received computes about 1655 years) almost as long a time as hath passed since the nativity of our Saviour: and this we cannot but conceive sufficient for a very large increase, if we do but affirm what reasonable enquirers will not deny: That the earth might be as populous in that number of years before the flood, as we can manifest it was in the same number after. And whereas there may be conceived some disadvantage, in regard that at the Creation the original of mankind was in two persons, but after the flood their propagation issued at least from six; against this we might very well set the length of their lives before the flood, which were abbreviated after, and in half this space contracted into hundreds and threescores. Notwithstanding to equalize accounts, we will allow three hundred years, and so long a time as we can manifest from the Scripture. There were four men at least that begat children, _Adam_, _Cain_, _Seth_, and _Enos_; So shall we fairly and favourably proceed, if we affirm the world to have been as populous in sixteen hundred and fifty before the flood, as it was in thirteen hundred after. Now how populous and largely inhabited it was within this period of time, we shall declare from probabilities, and several testimonies of Scripture and humane Authors.
